WARP- ND Ho nER Fen wARn imnMs t Application filed oct'ober 231 926] s n in 1439175. 'Q A This invention relates to warp beams for looms audit is the principal object ofjthe invention toprovide improved means for re taining the groups of warp threads so that any inequalities resulting from the tying in of the groups may be equalized,

\Vhen a silk warp isfastened to a beam the ends are divided into groups which are secured to some part of the beam. In my co-pending application Ser; No, 137,860 I have shown a beam having a hollow barrel with holes therein through which the groups of ends pass to be tied to a fiexible'cord inside the barrel. The threads in said application are tied directly, to the cord while a portion of the cord is projecting through one of the openings in the barrel. l/Vhen the next group is tied to the cord the first, group is drawn into the barrel by a motion on the part of the cord which draws the knot to ward the guide or holder for the cord. If the ends have been tied too; tightly and the amount of the cord extending beyond the periphery of the barrel is considerable the knot will not slip on the, cord, thus preventing the complete equalizing action vwhich is desired. It is an importantobject of my present invention to overcome this defect by introducing an element between the cord;

and the knotted warps which will overcome the friction between the fibrous cord and the warp ends. r

' It is a further object of my invention to provide a hollow barrel with a plurality ofhooks movable in fixed planes with respect to the barrel and arranged to project through openings to facilitate the tying of the warp ends, said hooks being in engagement with the flexible cord so as to compensate for any inequalities resulting from ty- "ing of the warpends' to the hooks.

It is a still further object of. my 'invention to provide hooks so disposed with regroups of warps will begreater. than iskpos sible where the. warp is tied directly to the cord, theadvantageresulting from the fact that the cordfengages the hook between the.

fulcrum thereof and the point where the warp issecured" thereto;

' With these and other objectsin "view ,which will'appear as. the description proceeds, my invention resides-in the combination and arrangement or parts hereinafter described and set forth in the claims.

In the; accompanying drawings whereinl I Referring to the drawings it will be seen that I have provided a hollow barrel 10 preferably metallic and having secured. at each end thereof a'fizged head 11 fromwhich projects a supportinggudgeon 12. False heads 13 having hubs 14 are longitudinally adjustable along the barrel-by means of screws 15 fitting spiral grooves 16.; i

sarily, so placed asto lie between adjacent holes 21 as shown in Fig. 3, The cord 20 may have" the" ends thereot'secured to the endfeyeletsil-Q by having knots tied therein. The matter thus far described may be substantially the same as set forth in my aforesaidapplication; i j

Insteadof tying thewarpendslV directly to the-cord 20f asin' my earlier construction I provideherein a plurality Of'llOOk menuhers 30 having a hookedend. 81 atone end thereof and a pair-of bearing ends. 32at the other :end' thereof; .saidbearings- 32 extending throughrigidreyes 3.3, similar tothe eyes 19-ancl mountedbn the barf17. Each hook member 30 is formed substantially as shown inFig. 2 with an angular portion indicated at 34 defining a notch for the cord 20. That "portion ofi-the'member 30 lying between the notch 3412\nd. thelhearings 32 should be formed in a manner similar to that set forth in the drawings so that the cord will at all times be retained in the notch} -heads 13 to engage the corresponding hook '31 andmove the same to the position shown in Fig. i, this motlon'being permitted by the slackness of the cord 20,; The first group of warp ends W is then secured'to this hook opening 21 to withdraw the second hook.

' This motion will be accompanied by straightening out the slack of the cord for the first book so that the latter-will move into the beam to the position shown in Fig. 2. This ize any unevenness, in the tension of the operation isrepeated until all the groups have been tied to the hooks, the slackness in the cord for the last hook being taken up by a slight bending ofthevcord between allthe eyes 19. iThis bending of the cord will depend upon the tightness or slackness otthe various groups and will tend to equalwarp threads. The hook member moves in a plane fixe'dwith respect to the beam andany longitudinal movement of the cord relatively thereto will --not move the warp threads-lengthwise of the barrel.

-An inspection of Fig. 2- shows that the 7 distance bet-ween thehooked end 31 and the axis of the'hooked' member is greater than the distance between said axis and the cord 20, so that the amount of: movement of the knots in the warp thread groups is greater 7 than the movement'in the cord, and consequentlythe compensation for uneven tying is greater than would be the case were the ends tied directly to the cord, as inmy aforesaid application.

In the modified form of 'theinvention shown in Figsr5, 6, and 7, there are set forth warp hooks and cord guides formed 'ofdwire. ,In carrying out this modification ofthe invention-I form each cord guide 4:0

as shown in Figs. 5 and 6 with a pair of spaced straight ends 41 which are driven into awooden :ba'r42 corresponding to bar 17. the wire being provided with loops-43 adjacent the wooden bar 42 near the point where the ends 41 enter the same, and I further provide each guidewith an eye a4:

to receive the cord 20. 1

' The hook member i5 has a pair of aligned short ends46 which pass into the adjacent eyes 42 jofadjacent guide members 40 tozbe pivotally mounted on said guides." i'lhe intermedlate portion of each ofsaid hooks 4L5 cord.

] nection with thepreferred form, the eyes 44:

being fixed andthe hook member 15 moving around the eyes 13 as centers when the hook is being projected through one of, the open ings 21 to receive agroup of warp threads.

I ,From the foregoing it will be seen that andv the tool T inserted through thenext' I have'provided a hollow warp beam having a flexible cord therein possessed of sufiicient slackness to-compensate for any unevenness which may result inthe tying in of-the sev eral. groupsof warp ends and that I have V interposedbetween each group and the fiexi- 'ble member a metallic or non-fibrous device which prevents the longitudinal movement of the flexible cord from moving the warp ends laterally against the guides for the It will further be seen that I have provided a hook member movable in a plane fixed relatively to the beam and having the f warpends tied. to one part thereof and being acted on at another part thereof by the eord. It will-further be seen that that part of the hook member which has thewarp ends secured thereto has a greater movement" than the part which is in Contact with the cord so as to permit a greater movement on the part of the warp endsto take up the unevenness thereof vthan is possible in my aforesaid application where the warps are attached directly to the cord.

Having thus described my invent-ion it wil'l'h-e apparent that changes and modifications may be made therein by thoseiskilled in the art without departing from the spirit and scope of the invention, and I do not wish to be limited to the details herein disclosed but what I claim is: i v

1. In a warp beam, a hollow barrel having passages through the/periphery thereof for groups of warp threads, a flexible slack member extending along the interior of the barrel, and a plurality of non-fibrous guides threads, ,a flexible slack member extending along'theiinteriorof the beam, a plurality of spaced guides for the member, and a movable toward and from one of the openings in the barrel and adapted to have tied thereto a group of Warp ends.

3. In a warp beam, a hollow barrel hav ing a plurality of openings in the periphery thereof, a flexible slack member extending along the interior of the barrel, a plurality of spaced guides for the flexible member, and a set of hooks pivotally mounted rela-. tively to the barrel on the interior thereof and having operative contact with the slack flexible member and adapted to extend through the opening to have the warp ends secured thereto.

l. In a warp beam, a hollow barrel having a plurality of openings in the periphery thereof, a flexible slack member extending along the interior of the barrel, a plurality of spaced guides for the member, and a plurality of hooks each to receive a group of warp ends and each movable toward and from one of the openings in a plane fixed relatively to the barrel and each having contact with a portion of the flexible member, to the end that inequalities in the tying of r the warp threads to the hooks may be compensated for by the slackness of the member,

5. In a warp beam, a hollow barrel having a plurality of openings therein, a flexible slack member extending along the interior of the barrel, a plurality of spaced guides for said member, and a'plurality of pivoted hooks movable toward andfitrom the openings and having ends to receive groups of warp threads, said hooks being formed to have contact with a portion of the flexible 'member at points nearer the pivots of said I hooks than the points at which the warp threadsare secured thereto,

6. In awarp beam, a hollow barrel having a plurality of openings therethrough, a flexibleslack member extending along the interior of the barrel, and a plurality of devices to have the warp threads tied thereto, and having contact with said flexible mem ber, said members being movable relativelyto each other to take'up unevenness in the tying of the groups of warp threads thereto and being limited in said relative movement by the slackness of the member, the movement of the warp ends relatively to each other being greater than the movement of the flexible member due to the slack thereof.

In testimony whereof I have hereunto af- 7 fixed my signature.
